SMART SENSOR ST6813 Handheld Illuminometer LCD Color Screen Digital Illuminance Light Lux Meter Measurement Tool Battery Operated Photometer Luxmeter with 180° Rotatable Probe Measuring Range Up to 100,000 Lux / 10,000 FC and 1pc Tool Bag for Indoor Plant Grow LED Lights

With measuring range up to 100,000 Lux and 10,000 FC, this handheld LCD digital illuminance meter designed with a 180° rotatable sensor, which can be applied for the photometric measurement of stage performance, mall, library, plant cultivation, headlight, production workshop, etc.

Features:
[Professional LED Light Meter] Visible light emitted by fluorescent lamp, metal halide lamp, high voltage sodium lamp or incandescent lamp can be measured.
[Wide Measuring Range] Measures luminosity from 1 to 100,000 Lux and 1 to 10,000 FC. 
[Accurate Measurement] High accuracy of ±(3%+5Lux) (at 2854K incandescent lamps); ±(6%+5Lux) others.
[Practical Function] Press the Data Hold button to freeze the displayed reading; auto/manual range for accurate measurement; unit conversion between Lux and FC is available.
[User-Friendly] Measures 7.32*2.16*1.18in and weighs 4.97oz, featuring compact and lightweight; photosensitive probe can be rotated clockwise in 180°; and LCD HD color screen ensures clear visibility even in low-light area.

Note:
*Batteries are not included.
*The 180° rotatable sensor is only turning toward the right.
*One Lux is the light received on the surface of a candle with a vertical intensity of 1 meters and an area of 1 square meters.
*One FC is the light received on the surface of a 1 inch square foot at a distance of 1 feet from a candle with a light intensity.
